. H it. VAN BORN, OF CHICAGO,

Be it known that I, WILLIAM T. VAN

ORN, a citizen of the United States and a resident of the city of .Chicago, in the county of Cook and State of Illinois, have invented certain new and useful lm rovements in Metal Car Construction; an I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawlugs, and to the numerals of reference marked thereon, which form a part of this specification.

etal'cars are superseding wooden cars in practically all types of rolling stock, but the chief objection to metal cars has been weight and high initial cost.

owever, the difference-in the cost of maintenance for repairs on the metal car as compared with the old wooden car, is almost suificient to offset the excess initial cost of manufacture of the metal car.

I have invented a metal car, in particular a freight car, which is not only a great deal stronger, and in fact of less weight than similar cars heretofore constructed, but is a so easily and cheaply manufactured. I construct a steel freight car by using a plurality of corrugated panels which are of a peculiar construction to form the end and side Wallsof the car, and which are constructed and joined together in a manner capable of affording a strong support for the roof structure of the car, obviating the use of corner posts and intermediate posts in the car structure.

Itis an object of this invention to construct a metallic car wherein the side and end walls are formed of a plurality of corrugated panel members, certain corrugations of which are of a peculiar nature permitting the end and intermediate posts of the car structure to be dispensed with and as well,

due to the parabolic nature of other of the corrugations, the panel members are capable of withstanding a termendous load.

It is also an object of this invention to construct a car built up of sheet metal panels so formed that when connected to one another a rib is formed on the interior and exterior of the car corresponding to the sup porting posts for the roof structure of an It is alsoan object of my invention to const uct a car at a p al ty f blo h t ILLINOIS, ASSIGNOR T0 VAN DOE/N GIJRDER PLATE COMPANY, OECHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

metal panels, ing the panels mounted uprightly thereon and the end Wall panels mounted lengthwise transversely, and with the meeting edges of said side and end panels formed in a certain manner and double riveted to one another affording a rigid corner not requiring an end or corner post as a part of the car structure.

It is also an object of this invention to construct a car, the side and end walls of which are composed of corrugated panels double riveted to one another and with reg- Patented Dec. ill, 191W. Application filed July 1%, 1914.. Serial No. 851,031. 1

the side walls of thecar havistering corrugations on the connected edges of adjacent panels disposed between the rows of rivets, the double thickness of metal and the corrugated portions thereof acting as, and in the place of the usual posts of the car structure.

It is furthermore an tion to construct a car embodying a plurality of panel members, said panel members having corrugations therein of varying depth.

It is finally an object of this invention to construct an extremely durable car, relatively light in weight and of low cost to manufacture.

The invention illustrated in the drawings and hereinafter more fully described.

As shown in the drawings:

The reference numeral 1 indicates the side sills of a car underframing, which at their ends are attached to, in a customary manner,

Side plates 3, extend longidbject of this inven- (in a preferred form) is mounted intermediate the side plates 3, parallel thereto, and together with said side plates afford a support for a roof 6, mounted on the top of which is a running board 7 A downwardly directed angle iron 8, is secured along the under surface of the end. plates 4, and together with said end sills 2, afl'ords means of attachment for a sheet metal car end comprising oblong panels 9 and 10, respectively, extending lengthwise across the end of the car. Said panel 10, is attached along its upper margin by means of rivets or bolts to said angle iron 8, and along its lower margin is corrugated outwardly, as designated by the reference numeral 11, to register with a similar inwardly stamped corrugation 12, on the upper margin of said lower panel section 9, with a row of rivets 13 and 14, respectively, on each side of said registering corrugations.

The side walls of the car are also constructed of a plurality of oblong corrugated panels, the intermediate panels of which are designated by the reference numerals 15 and 16, and the end or corner panels by the reference numeral 17 The panels 15 and 16, are exactly identical in construction, and the only difference between these panels and the panels 17, is that one margin of each of the panels 17, is corrugated outwardly, as indicated by the reference numeral 18, and bent inwardly at a right angle to engage around an inwardly directed flange 19, on the end of the respective lengthwise end panels 9 and 10, and is riveted by means of rows of rivets 20 and 21, on each side of the corrugations so that a very rigid corner is obtained, not requiring the further reinforcement of an end or corner post. Each of said panels 15 and 16, on one side thereof is provided with an outwardly stamped corrugation 22, and on the opposite side or margin with a similar inwardly stamped corrugation 23, so that when said panels are assembled with one another the respective outwardly and inwardly stamped corrugations 22 and 23, are in register. The panels are riveted on each side of said corrugations by rows of rivets 24 and 25, respectively, affording a rigid rib on the interior and exterior of the car at a point of double thickness in the walls thereof, thus obviating the necessity for intermediate .posts in the car structure.

Each of said panels 15, 16 and '17 along its upper end is secured in any suitable manner to the side plates 3, and at its lower end is similarly secured to the side sill 1.

' Secured over the upper margins of each. of the side panels, is a side fascia board 26, and likewise an end fascia board 27, extends over the'upper margin of the end panels 10. Similarly the lower margin of the end panels 9, have secured thereover by bolts extending through the panels and through the and sills 2, a bufiing block 28.

The corrugations in each of the side and end panels are of a peculiar nature. As clearly shown in the drawings, the corrugations extend longitudinally of the panels and at their ends are made continuous'by curved portions joining the corresponding straight longitudinal portions of the corrugations. The'particular point of note, however, is the construction of the straight portion of the corrugations, which, as clearly shown. in the sectional figures, is of a varying depth, and inasmuch as the variation in depth of the respectivecorrugations is symmetrical, the point of greatest depth of the corrugations in the panel is substantially at the middle thereof. This form of. corrugation is a great deal stronger .than the usual corrugation of constant depth, and in fact each one of the corrugations acts as a beam member which is comparable with the well known type of parabolic beam of uniform strength. The ease with which the various panel members may be assembled and connected to one another is apparent, and the registering oppositely directed corrugations in the margins of the connected adjacent panels combined with the double rows of rivets provides a construction which affords in itself, frame members for the car structure, obviating the use of the usual end and intermediate posts.

I am aware that various details of construction may be varied through a wide range without departing from the principles of this invention. I therefore do not purpose limiting the patentgranted otherwise than necessitated by the prior art.

I claim as my invention:

1. In a car structure of the class described oblong sheet metal panels forming the end and side walls of a car, the end wall panels disposed lengthwise transversely of the car, and provided with corrugations of varying depth, increasing in depth toward the middle of the panel, the end margins of said end panels angled inwardly substantially at right angles to the plane of the end of the car structure, and the side panels disposed in upriglit'position, the side end margins of the end side panels corrugated outwardly and arched around the inwardly bent margins of the end panels and riveted thereto on each side of said bends in the margins of the end panels afi'ording a rigid corner for the car structure.

2. In a car structure of the class described, end panels having corrugations of varving depth formed therein and with the side margins of said end panels bent inwardly substantially at right angles to the plane of the end of the car structure, corrugated side panels corrugated continuously throughout the length thereof and with the end side panels having a marginal corrugation fitted around the inwardly turnedmargins of the throughout each of the panels masses end panels and spaced therefrom and secured thereto along two li-n s of'contact to afford corner posts for the car structure.

3. A car structure of the class described comprising corrugated end panels with the corrugations extending transversely of the car and the" side margins of the panels bent inwardly to form a corner, and with the line of-bend at right angles to the line of corrugation in said panels, and side panels having corrugations extending lengthwise and with the end marginpf each of the end side panels corrugated around the inwardly bent portion of the margin of the end panels, and a double line of rivets securing said corrugated margins of the side panels to the end panels to afford corner posts for the car structure.
